Abstract

A multiplex type transmitting apparatus is arranged to have a plurality of slow signal receive/transmit sections for accommodating a counterpart for a SONET system or an SDH system, a multiplex separation converting section , and a receive/transmit section for a SONET system or SDH system fast signal. The slow or fast signal receive/transmit section includes a receive processing unit on a receive the for receiving the SS bits of the SONET/SDH system signal received from a transmission path , an internal SS bits setting unit for setting the SS bits of the received signal to internal SS bits if the SS bits of the received signal are "10" or "00", a transmit processing unit on the receive the for transmitting a signal to the multiplex separation converting section as keeping the SS bits as "11" when an AIS-P is transferred , and a transmit processing unit on a transmit the for transmitting the signal from the multiplex separation converting section onto the transmission path as keeping the SS bits identical with the internal SS bits.
